UPDATE (May 31st, 2019):
Google has re-added Huawei Mate 20 Pro to the list of eligible devices for Android Q beta. It was removed from the list last week after the US government announced a ban on the company. With the reinstation, the Mate 20 Pro should be receiving the latest Android Q beta anytime soon. It also suggests the phone is likely to receive the stable version as well.

This year's Android beta program is the biggest one when it comes to the number of eligible smartphones. There are phones from different OEMs but as per recent reports, one of the phones have been removed from the list. It is the Huawei Mate 20 Pro that was part of the original eligible devices list but has disappeared now.
The official Android Q beta devices page offers a list of devices from all OEMs that can be used for installing the latest beta. It has removed all the mentions of Huawei Mate 20 Pro suggesting that Android Q beta will not work on the flagship anymore. It seems like the removal has come because of the ban the US government has announced on Huawei.
It is soon after the ban announcement that Google confirmed cutting off all ties with the Chinese technology giant and world's second-biggest smartphone maker. It revealed that Huawei phones will not be receiving any software support including Google Play apps and services.
Even though Huawei has received a 90-day reprieve from the government but that does not seem to have had any effect on Google's stand. The smartphone maker itself is not taking anything lightly and has already started preparing for the worst case situation. It has been reported to be in talks with Aptoide for replacing Play Store on its smartphones. The company also has its own operating system under works.
In a nutshell, there is a possibility that the ban might get overturned but Huawei does not want to take any chances and is preparing for a life without Google and Android.
